Ok Guys i have got the solution myself..just posting it here incase if some one else comes across the same problem, they can get idea about how to solve it.

I downloaded tls llibraries manually from sourceforge.net. after this i extracted them to /home/amsn/plugins/ (this is the locaiton of amsn and /plugin directory on my machine). after extracting it became some thing like /home/amsn/plugins/tls1.4 .

the files in /tls1.4 looked like this

libtls.1.4.so

pkglindex.tsl

tls.tcl

okay after extracting, i restarted amsn and still it didnt work. this time it said "host unreacheable". Then i went to preferences -> application in amsn and gave the path of tsl libraries i.e /home/amsn/plugins/tls1.4. Then i restarted amsn again and it worked.
